. END ANCHORAGE Eon TANK-cans.

To all whom it may concern:

Be it known that I, GEORGE F. WOOD- SMITH, a citizen of the UnitedStates, re siding in the city of Pittsburgh, county of Allegheny, Stateof Pennsylvania, have invented a new and useful End Anchorage forTank-'Cars, of which the following is-a specification.

I My present invention consists of a novel construction of an endanchorage'for tank cars wherein provision is made for taking up the wearof the wooden head block, or the.

contraction of thetanlqor to overcome defective workmanship in fittingthe head block to the curvature of thetank.

' It further consists of a novel construction of an adjustable endanchorage in which a buffer and chafing casting is employed for tyingthe centersill channels together, and which also acts as a bufier forthe coupler to strike against and as an abutment for the head blockbracing member with which the wedges cooperate to compensate for thelongitudinal movement of the tank. v

It further consists of novel means for locking the wedges in theiradjusted position, and also novel means foreliminating in a largemeasure the shearing strain on the rivets and changing the shearingstrain to a tension strain. l I

It further consists of a novel construction of a buffer, a novelconstruction of brace members, a novel construction of wedges, a novelconstruction of a channel, a novel arrangement of such parts, and othernovel features of constructiomall as will hereinafter morefully appearin the detailed description of my invention. For the purpose-ofillustrating my invention, I have shown in the accompanying drawings oneformthereof which is at present preferred by me, since the same has beenfound in practice to give satisfactory and reliable results, although itis to be understood that the various instrumentalities of which myinvention consists can be variously arranged and organized and that myinvention is not limited to the precise arrangement and organization ofthese instrumentalities as herein shown'and described.

Similar numerals of reference indicate corresponding parts in thefigures. Referring to'the drawings.

1 and 2 designate the center sills which carry the bolster 3. 4designates the tank which is supported in any desired manner. 5designates the wooden head blockwhich is recessed asindicated at 6, inorder to conform to the movement of the end of the tank, said head blockbeing mounted on plates or bars 7, carried by the center sills, suchbars termlnating at 8 and said head block being angularly recessed as isindicated at 9.

l0 designates a channel beam which abuts against the wooden head block5. 11 are stay rods passing through the head block and the channel 10,as will be understood by'reference toFig. 1, and provided with nutsl2,and turn buckles 13 which also engage in the usual manner the rods 14,the outer ends of which are flattened as indicated at 15 in order thatthey may be secured to the bolster 3 by means of fastening devices 16 ofany desired type. I l7 designatesabuifer and chafingcastlng which isprovided with a striking "plate 18 which is preferably curved asindicated at 19, in Fig. 3, and is provided with a flange 20 aperturedas indicated at 21 in order to receive the fastening devices 22. Thecasting 17 is provided with an upwardly extending lip 23 which extendsabove the laterally extending top face 24, the forward'end of whichisotfset 'as'indicated at 25in order that the'samemay be seated on theend of the plate or bar 7 andsupport the channel 10, it beingunderstood'that two of the offset portions 25 are provided and that thesame are fastened to the center sills by means of rivetsor equivalentfastening devices 26, which also pass through the plate 7. 2 Thelaterally extending portions 24: of the'buffer casting 17 are adaptedto-support the head block brace or casting 27, therear plan view of Fig.4 represents an end elevation of face 28 of which is adapted to abutagainst the lip 23 while the forward face thereof is inclined asindicated at 29, and provided with an angular shaped receSsBO, the wallsof which are also inclined, thereby adapting the same to receive thebottom flange 31 which runs along the length of the wedge 32, it beingbest understood by reference to Figs. 1 and that the outer faceof theflange 31 is inclined as indicated at 33, and the latter being adaptedto :coact withthe inclined face 29 of the head block casting 27.Theinner face of the wedge 32 is preferably cored out as indicated at35, thereby forming the rectilinear 121C636 which engages with the innerface 37 of the channel 1'0. The top and bottom faces of the wedge 32which are preferably inclined as seen at 38 and 39 respectively, in Fig.7, it being understood that the face 39 is adapted to travel on thelower flange of the channellO. l

Each wedge 32 is provided with a boss or lug 40 having a desired numberof apertures 11 therethrough, it being apparent from Fig, 1 that thechannel 10 is provided with apertures e2, through which are adapted topass fastening devices as, In practice the apertures in the wedges andchannel are placed at difierent distances apart in order to providemeans for locking the wedges "in their adjusted position after slightadjustment of the wcdge's, V

The head block casting 27 is secured in position with respect to thecenter sills by the rivetsee, which also serve as means for securing thebuffer casting 17 to the center sills, The rivets on the inside of thehead block casting 27 do not pass through the center sills 1, but simplypass through the headblock casting 2-7 and the buffer casting 17, willbe understood by reference to Fig. ,1, The buffer casting 17 is alsoprovided with a reinforcing flange e6 in order that the center sills 1and 2 may fit therein, as will. be understood by reference to Figs. 2and 3.

I It will now be apparent that in case there is wear between the headblock and the tank, or contraction has taken place in the wooden headblock, or if the head block has not been properly fitted 'to thecurvature offthe tank, the wedges 32 are driven in and in ordertoprevent them slackening ofi due to vibrations in, transit, the fasten-?ing devices such as pins 7 13, are placed through the apertures 42 andthe apertures 41 registering therewith. 7

Special attention is directed to the novel construction and cooperationof these wedges andalso the manner in which the "flange 31prere'ntsthe-lifting or rising of the wedges. Special attention'is alsodirected to the lip 23 which takes a part of the shearing strain'ofi'the rivets and also changes the shearing strain on the rivets to atension strain.

The turn buckles 13 may be adjusted as desired, in order to take up anyslack in the tie rods 11 and 14.

It will'now be apparent that I have devised a novel and usefulconstruction of an end anchorage for tank cars, whicheim bodies thefeatures of advantage enumerated as desirable in the statement of theinvention and the above description, and while I have, in the presentinstance, shown and described, a preferred embodiment thereof which hasbeen found in practice to give satisfactory and reliable results, it "tobe understood that the same is susceptible of modification in va-riou'sparticulars without departing from the spirit or scope of the inventionor sacrificing any of, its advantages.

Having thus described my invention, what I claim as new and desire tosecure by Letters Patient 'is-: 1
